A variety of terrestrial small mammals with diverse size, form, geographic range, and ecological niche inhabit southern forests. Some are highly specialized for their environment, such as the semi-aquatic species or fossorial species, such as moles. Some, such as the cotton rat, are widely distributed throughout the region and others highly restrictive in their range and habitat. Because of the...

The ability of diving mammals to forage at depth on a breath hold of air is dependent on gas exchange, both in the lung and in peripheral tissues. Anatomical and physiological adaptations in the respiratory system, cardiovascular system, blood and peripheral tissues contribute to the remarkable breath-hold capacities of these animals. The end results of these adaptations include efficient venti...

Birth of babies through in vitro fertilization procedures has Tenewed interest by clinicians as well as laymen in the phenomenon of fertilizatien. In most medical text books, fertilization is treated very lightly giving students the impressien that fertilization is a simple mechanical penetration of a spermatozoon into an egg. This is far frorn the truth. Fertilization comprises ・a series of co...

The understanding of how environmental exposures interact with genetics in central nervous system dysfunction has gained great momentum in the last decade. Seminal findings have been uncovered in both mammalian and non-mammalian model in large result of the extraordinary conservation of both genetic elements and differentiation processes between mammals and non-mammalians. Emerging model organi...

although the mechanisms under which sex ratio is controlled in nature remain unknown, researchers have attempted to treat sperm in an effort to predetermine the sex of the offspring. the methods of sperm separation that have been repeatedly reported to isolate fractions rich in x- or y-chromosome bearing sperm are serum albumin gradient swim-up and flow cytometry. however, the ability of the se...

The phenomenon of terrestrial mammals as predators in marine intertidal communities, and thus as agents of energy transfer from sea to land, is poorly understood. We review here the evidence for terrestrial mammals intentionally entering the ocean shore at low tide in order to prey on living marine invertebrates, fish, algae, and seagrasses. We introduce the term ‘maritime mammals’, defined as ...

This paper deals with the preliminary observations of the analysis conducted on the faunal remains unearthed at thesite of Shikarpur. A single trench ES4 was selected as a research sample from the excavation conducted by theDepartment of Archaeology and Ancient History; M.S. University of Baroda, Gujarat State, India in 2007-08. Atotal of 6250 skeletal fragments were analysed of which only 3219...

Synaptic plasticity in the central nervous system (CNS) of mammals has been discussed for many years. Several forms of synaptic plasticity of mammal’s CNS have been identified, such as those that occur in long-term potentiation (LTP). Different types of LTP have been observed in distinctive areas of the CNS of mammals. The hippocampus is one of the most important areas in the CNS that pla...
